Abstract

AIM:

Post-traumatic emotional distress follows exposure to trauma and may be affected by atypical cerebral lateralisation. We aimed to explore the relationship between handedness and emotional dysfunction in people exposed to a nat-ural disaster.

METHODS:

About 22 months after an earthquake, 326 exposed adults completed the Edinburgh Handedness Inventory, the Impact of Events Scale-Revised, and the Insomnia Severity Index.

RESULTS:

Mixed-handed people, compared to right-handed, had a 3.3 fold increase in odds to have emotional distress. Consistent left-handers scored higher than consistent right- and mixed-handers on the ISI scale.

CONCLUSIONS:

Findings support that lateral preference is associated with emotion-al distress in people exposed to trauma.
